CALPUFF Control File Inputs - Input Group 15
Line Source Parameters
Variable Type Description Default Value
(Input Group 15c - Variable Emissions Scale Factors)
SRCNAM character*12 Source name, used to coordinate inputs in Subgroups b,c
-
IVARY
integer
Type of scale factor variation (diurnal, monthly, etc.)
0 = Constant
1 = Diurnal cycle
(24 scaling factors: hours 1-24)
2 = Monthly cycle
(12 scaling factors: months 1-12)
3 = Hour & Season
(4 groups of 24 hourly scaling factors,
where first group is DEC-JAN-FEB)
4 = Speed & Stab.
(6 groups of 6 scaling factors, where
first group is Stability Class A,
and the 6 speed classes have upper
bounds (m/s) defined in Group 12)
5 = Temperature
(12 scaling factors, where temperature
classes have upper bounds (C) of:
0, 5, 10, 15, 20, 25, 30, 35, 40,
45, 50, 50+)

QFAC real array Array of emissions scaling factors for this source and the
species indicated
-
The variables in Input Group 15c are entered for each line source - species combination indicated by
NSLN1 in Input Group 15a (e.g., only NSLN1 combinations are entered). The data for each line sourcespecies
combination (i.e., source name, type of variation, and the QFAC array ) are treated as a separate
input subgroup and therefore must end with an input group terminator (i.e., !END!). Once again, the
source number is an optional user comment which is outside of the delimiters. The source name is used
to place the scaling factors with the correct source. The data for each source-species combination must
follow an opening delimiter and "(cspec)=", where (cspec) is a species name defined in Group 3. The
data for each source-species combination is followed by a closing delimiter and an input group terminator
(i.e., !END!). If NSLN1=0, no scaling factors should be defined here.
